How do you avoid wasting Bones in Mina the Hollower?

Short Explanation

Bones are most valuable when they remove a real bottleneck. Before buying, decide whether the current problem is damage, survival, route clarity, farming speed, or late cleanup, then spend toward that goal.

Quick Tips

• Choose upgrades with a clear purpose.
• Do not farm without a specific purchase target.
• Save completion tools for cleanup unless they solve an immediate issue.
